>Right. There are two kinds of DLLs that you can call -- API-style DLL calls, and COM. The first type are created in C, C++, Delphi (?) and are assigned with SET LIBRARY TO --- the second can be created in VB, VFP, etc. and are called by another program via CREATEOBJECT().


Not really. .FLL files are added via SET LIBRARY, and are direct extensions of VFP working with a special API that exposes VFP's internals to the .FLL; standard C-style .DLL files get referenced by using DECLARE...DLL to produce references to DLL entrypoints; things not passed as parameters to a standard .DLL are not visible; FLL code can access VFP's internal NTI, and actually call VFP native commands within the FLL
